The spread of ride-hailing services and autonomous vehicles will lead to higher energy demand, a study finds. Electric vehicles and a much cleaner grid are the only way to avoid more emissions.
Hurricanes Michael and Florence have knocked power out for millions of people. Burying power lines could help but the costs are high.
Fifteen years after the Northeast Blackout of 2003 cut power to 50 million people in the US and Canada, experts explain that many threats to the electricity grid remain.
Power utilities' cybersecurity practices may be effective, but need to evolve over time. And all companies operating elements of the grid – even the small ones – should step up.
Experts explain the task of securing the electrical grid against cyberattacks, and discuss potential solutions and the risk of failure.
Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Energy storage, such as big batteries, on the power grid is generally seen as 'green' technology but the reality is more complicated, an analysis finds.
Yes, Puerto Rico and any other storm-vulnerable location could benefit from on-site solar and battery backup, but it's unrealistic to say these microgrids are enough to power the island.
Two moves by the Trump administration signal a dramatic shift in energy policy to favor coal and nuclear, but markets forces and legal challenges mean changes could take years.
The price of renewable energy will fall significantly relative to new-build coal in coming decades, making an all-renewable electricity system more desirable, both economically and environmentally.
US military bases usually get their electricity from the civilian grid, which is vulnerable to attack and to disaster. Solar-powered microgrids could protect national security, and would save money.
The centralised regulation of electric power in Nigeria is stalling progress in the sector. To achieve stable power supply, the country must obey its constitution and decentralise regulation.
A year after Brexit, experts from the Grenoble École de Management and the Centre for European Economic Research look at what impacts the UK's leaving the EU could have on energy prices and security.
Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Trump has pledged to invest big in infrastructure. An analysis shows the electric grid will need hundreds of billions of dollars over the next decade just to keep things as they are.
The power grid is increasingly computerized. That opens it to attacks and requires new defenses.
Past attempts to help Latrobe Valley workers weather economic changes haven't made a difference, so the closure of Hazelwood presents a challenge.
Kangaroo Island's electricity link to the mainland needs replacing. But a new analysis shows that for roughly the same price, the island could move to independent, local renewable energy sources.
How bad are things for U.S. coal? Very bad, but that's very good for environment. Now the question is whether other countries will cut back on coal as well.
